The Mobile App for iOS Accessing your files on your ownCloud server via the Web interface is easy and convenient. You can use any web browser on any operating system without installing special client software. However, the ownCloud iOS app offers several key advantages over the web interface; these include: • A simplified interface that fits nicely on an iPhone or iPad • Upload files easily from your device to ownCloud • An Optional PIN for stronger security • Share files with other ownCloud users • Automatic synchronization of your files 1
Getting the ownCloud iOS App To get the ownCloud iOS App, point Safari, or your favorite web browser, to your ownCloud server. Next, log in and navigate to Settings › General (Personal). At the bottom of that page, you will see a link to the ownCloud app on iTunes. Links to ownCloud’s mobile apps. You’ll also find links and information on the ownCloud installation page. 2
Managing User Accounts Introduction With the iOS app, users can access their data from several ownCloud instances. They can use one or more accounts for the same server, or accounts for other ownCloud servers they have access to. Authentication Methods The iOS app supports two ways of authentication options for user accounts. These are: • Basic Authentication • OAuth 2.0 Authentication Options Basic Authentication • Login Credentials are stored on the device (secured in the iOS system keychain). • Password manager support. 3
OAuth 2.0 The OAuth2 implementation uses SFAuthenticationSession, which is described as a best practice by RFC 8252 - when running under iOS 11. Under iOS 12, the OAuth2 implementation uses ASWebAuthenticationSession, which is the successor of SFAuthenticationSession. Benefits of using these APIs include: • Privilege separation: Web content is run in a separate process. • Trustworthiness: Apps can’t inject code into or access the contents of the web view. • Convenience for the user: Cookies from Safari are available to the web content inside the session. Additionally, OAuth2 is the industry standard authorisation method, and the username and password are not stored on the device. Manage Accounts Add an Account To add one or more user accounts to the iOS app, when in the "Accounts" view, click the plus (+) icon in the top right-hand corner. This opens the "Add Account" dialog, where you can enter the URL of the ownCloud server. After you enter it and click "Continue", the iOS app checks the authentication method and the validity of the SSL/TLS certificate (if the server URL uses the HTTPS protocol). If the certificate is deemed to be valid, you will see a green "Passed" symbol near the bottom of the page, next to "Certificate Details", and the text "No issues found. Certificate passed validation." 4
Click [ Continue ] and the app will prompt you if you want to use the supplied server URL to sign in to the app. You will then be redirected to the ownCloud server, where you can supply your username and password. After doing so, and submitting the form, you will then be asked if you want to give permission for the app to access your account. • If so, click [ Authorize ]. • If not, click [ Cancel ]. • If you clicked [ Authorize ], you will then be returned to the Accounts screen, where you will 5
see your new account in the list. ownCloud server must have the OAuth2 app installed, configured, and enabled to use Two-Factor Authentication. Please contact your ownCloud administrator for more details. Delete an Account If you want to delete an account, when viewing the Accounts list, swipe left on the account that you want to delete and click [ Delete ]. You will then be asked if you really want to delete that account. If you do, click [ Delete ]. Doing so deletes the account from the device, as well as all locally stored file copies. If you don’t want to delete the account, click [ Cancel ]. Edit Authentication If you want to edit an account, when viewing the Accounts list, swipe left on the account that you want to edit and click [ Edit ]. 6
You will then be able to change the ownCloud server URL, and manage the authentication credentials. How the authentication credentials can be managed depends on the authentication type. Basic Authentication OAuth2 Authentication The user is authenticated using Basic The user is authenticated using OAuth2 Authentication. In this setup, they will be able to authentication. In this setup, they will only be enter a different password, as well as delete able to delete their OAuth2 authentication. their authentication data. 7
Configure Settings Introduction This document describes which settings are available and how to set them Settings Screen To manage the settings in ownCloud’s iOS App for iPhone and iPad, click [ Settings ] in the bottom right-hand corner of the Accounts List view. Security Passcode To protect access to the iOS app with a Passcode, enable [ Passcode Lock ] in the Setting’s Security section. You will then be prompted to enter, and repeat, a 4-digit Passcode. If a Passcode was set, the file provider extension in Files.app or in other third party apps will be locked too. The file provider presents a UI to unlock the Passcode. 8
Lock Delay When a Passcode is enabled, the app will be locked every time you change to another application. However, under Settings › Security › Lock application, you can choose to only lock the application after 1, 5, or 30 minutes, instead of "immediately", which is the default. Biometrical Lock After a Passcode has been created, a Biometrical Lock, or Touch ID, can also be used to gain access to the app. To enable it enable [ Touch ID ] in the Setting’s Security section, and then enter your 4- digit Passcode. The next time you need to authorise access to the app, you will be able to enter either your Passcode, or use your stored biometrical data. 9
Trusted Certificates View Previously Approved Certificates To view previously approved certificates, navigate to Settings › Certificates (for any one of your registered accounts), and you will see them listed in the "User-Approved Certificates" section. Inspect Previously Approved Certificates Details To view previously approved certificates, swipe left on any of the accounts in the accounts list and click [ Edit ]. Then, under "SERVER URL", click [ Certificate Details ]. You will then be able to see all of the certificate’s details. Revoke Previously Approved Certificates To revoke one or more previously approved certificates, first navigate to Settings › Certificates (for any one of your registered accounts). Then, in the "User-Approved Certificates" section, swipe left on the certificate(s) that you wish to revoke and press [ Revoke approval ]. Themes The iOS app comes with three themes: • Light 10

Media Upload (Conversion) When image and video files are uploaded, they can be converted to the industry-standard JPEG and MP4 respectively. This is not done by default. Image To convert (the very efficient) HEIC (High Efficiency Image File Format) images to more compatible JPEG images, enable [ Convert HEIC to JPEG ] under Settings › Media Upload. Video To convert the very efficient videos to more compatible MP4 videos, enable [ Convert videos to MP4 ] under Settings › Media Upload. 12
Managing Files Introduction The IOS app provides a number of features designed to make managing files as simple as possible. Features • File list filter • File sort options • Thumbnails for supported images • File quota (only displayed in the root folder) • File actions • Folder actions • Select all/none Click on a file to view it and click on a folder to view its contents. To view further actions available for a file or folder, click the More icon on the far right-hand side. File Actions The actions available for files are: • Open in 13
• Move • Rename • Duplicate • Copy • Delete • Make Available Offline However, file actions are handled slightly differently, depending on whether one or multiple files have been selected. You can see the differences in the two images below. Individual File Actions Multiple-Selected File Actions File popup for actions for individual files Move icon row for multiple-selected files Navigate Folders There are two ways to navigate folders (outside of the root folder). To go back to the parent folder, tap [ Back ] in the top left-hand corner. To navigate directly to any parent folder, tap on the current folder’s name. When you do, you will see the names of all the parent folders, right up to the root folder, as in the image below. 14
Navigate Files When navigating files, as you would expect, you can scroll up and down the files and folders list. In addition, you can also use the index bar, highlighted in the screenshot below, to speed up traversing through files and folders. As you slide your finger over each letter, you’ll jump to the first file (or folder) that begins with that letter. The index bar is only visible, if the sort order is Name. Sort Files and Folders By default, files and folders are sorted by name in ascending order, with folders sorted before files. However, files can be sorted in ascending and descending order by name, type, size, date, and shared. If you press the Sort by menu, you can change sort method and order. The first time you change the sort category, files and folders are sorted using that category in ascending order. If you 15
choose that category a second time, the sort order is inverted. Sorting files and folders in portrait mode Sorting files and folders in landscape mode View Files To view a file, tap on its name in the file list. Any file type supported by iOS Safari can be displayed in the app. Depending on the file type, the image will be able to viewed, or an icon for it, along with some file details, will be displayed. If the file is not available locally on the device, you will see next to the file. When you click on it, you will see next to it while it downloads. Table 2.

Storage Locally available file copies can be set to be automatically deleted after a specified period, ranging from 1 minute to 30 days, to clean up device space. The default is seven days. This is available under Settings › Storage › Delete unused local copies. This setting applies to all local files, not just available offline files. 25
Collaboration and Links Introduction This section shows how to collaborate with other users and how to work with links. Collaborate With Other Users on Files and Folders The Mobile App for iOS supports the following collaboration functionality: • Adding users and grant permissions • Adding groups and grant permissions • Changing permissions • Deleting collaborators Manage Links Grant Access With Links Just as with the web interface, the iOS app lets you grant access to both files and folders with links. Specifically, you can do the following: • Copy private links • Create public links • Set passwords and expiration dates • Send public link URLs to other apps (mail, messenger) • Delete public links 26
Copy Private Links To copy a private link to a file or folder, click the more icon on the far right-hand side of the file, and then click [ Links ]. As in the example below, you will then see the private link to the file. Clicking [ copy ] on the far right-hand side will copy the link to the iOS clipboard. Create Public Links To create public links to a file or folder, click the more icon on the far right-hand side of the file, and then click [ Links ]. Then, under Public Links, click [ Create Public Link ] in the Public Links section. You will then see the links for the option, as in the image below. As with the web interface, you can set: • A link name • Link permissions • A link password and expiration date To see more details about each option, click the info icon in the bottom right-hand corner. Set Passwords and Expiration Dates 27
To set a password on a public link, under "Options", enable [ Password ]. Then, type a password in the field that appears below the Password option. To set an expiration date on a public link, under "Options", enable [ Expiration date ]. Then, pick the date that the link should expire with the date picker that appears below the Expiration date option. Send Public Link URLs to Other Apps To share a public link URL via other apps: 1. Open the Public Link’s details. 2. Click the share button at the bottom left-hand corner, which opens the iOS Share Sheet. 3. Share the link through the app of your choice. Delete Public Links There are two ways to delete a public link. 1. When viewing the list of links for a file or folder, swipe left on the link that you want to delete, and click [ Delete ]. 2. When viewing the Public Link, click [ Delete ] at the bottom of the page, under [ Copy Public Link ]. 28
View Public Links The quickest way to view Public Links is by navigating to Quick Access › Shares › Public Links. There, you will see a list of files and folders that have Public Links. For any of the files and folders, click the More icon, where you will see the number of links for that file or folder. 29
Quick Access Introduction The app allows you to quickly access the key aspects of the application, by clicking [ Quick Access ], located in the footer of the application. Quick access is broken down into two sections: Shares and Collection. Shares Shares, as the name implies, lets you quickly see all files that are: Shared with you See a list of all resources you accepted from other users. Shared with others See a list of all resources where you invited collaborators. Public links See a list of all resources where you created links. Collection Collection gives you quick access to: 30
Recently accessed files These are files that were used sometime within the previous week, where used covers when it was imported, locally update, or was download. Files marked as favorite See a list of all resources in your account set as favourite. Files available offline See a list of all files and folders in your account that are available offline. Image files See a list of all image files in your account. PDF files See a list of all PDF files in your account. 31
iOS App and iOS Files App Integration and 3rd Party Apps Introduction The Mobile App for iOS integrates with the iOS Files App. When enabled, you can open, edit, save, and delete files and folders. However, the functionality needs to first be enabled. Work With Your ownCloud Data in iOS Files App To enable this possibility, click [ Browse ], then [ Edit ]. Next, in the list of apps under Locations, enable the ownCloud app for your account. In future versions, it is expected that the following functionality will also be supported: • Share (UI) • Offline (UI) • Favourites • Tags Share From Other Apps (via iOS Files App) When the iOS app is installed and at least one account is properly configured, files on your iOS device can be shared with your ownCloud server. To do so, first enable the location from the Locations list (step through how to do this). After that, when sharing a file, first click [ Save to Files ], choose a location to store the file, and click [ Add ]. These steps are shown in the three images below. Enable the ownCloud app as an Pick a file to "Save to Files" Pick the location to save the file iOS Files app location and click "Add" 32
Task Scheduling Introduction Background tasks are scheduled based on the app’s current context, and that context is based on a combination of factors. These factors include: • Is the app backgrounded or in the foreground? • Is WiFi available? • Is the device in Low Power Mode? • Is the device connected to external power? • Has the photo library changed? Tasks Currently, two tasks are available: • Instant photo uploads: This task is triggered when: ◦ The photo library has new photos, and; ◦ The user is connected to a WiFi network • Bookmark update task: This task is triggered by the background fetch event scheduled by iOS Instant Photo Upload There are some things to be aware of, regarding Instant Photo Upload. • Photo and video upload can be enabled and disabled separately. • Before instant media upload can begin, the account and upload path have to be selected • Changes in the photo library are detected when the app goes into the foreground. • If a user removes the folder specified for instant upload, the upload task silently exits. • When a user first activates instant upload, the timestamp of the activation is stored and compared against the creation date of the assets to be uploaded. As soon as one asset is successfully uploaded, its creation timestamp is used to update the instant upload activation timestamp. This: ◦ Prevents assets being uploaded twice ◦ Removes the need to keep track of uploaded items in a database ◦ Please note, that already uploaded and edited asset is not going to be uploaded again • Media conversion settings are taken into account by instant upload feature. 33
Security Introduction This document provides an overview of the security considerations and features in the new ownCloud iOS SDK and new ownCloud iOS App. Authentication API The ownCloud iOS SDK (2018) is a general-purpose API for implementing passphrase- and token- based authentication methods, which provides three key benefits. These are: 1. Ensures structural separation of code between general connection-handling and authentication. 2. Simplifies code reviews, by limiting each implementation to one class each (e.g., OAuth2, BasicAuth). 3. Ensures extensibility. Secrets Authentication secrets contain information such as usernames, passwords or tokens, and are generated by the respective authentication method implementation. Authentication Secrets are securely stored in the app’s Keychain and tagged as AccessibleAfterFirstUnlock. They cannot be accessed after a restart until the device has been unlocked once by the user. Supported Methods Authentication method implementations are available for OAuth2 and Basic Authentication. Method Selection After performing auto-detection, identified authentication methods are filtered and ranked by preference. The method with the highest ranking is then picked for the user. By default, all detected methods are considered and OAuth2 ranks higher than Basic Authentication. Filtering and ranking can be customized by MDM Configuration. This, for example, allows making OAuth2 the only possible authentication method, so no credentials need to be stored on the device. OAuth2 Implementation The OAuth2 implementation uses SFAuthenticationSession, which is described as a best practice by RFC 8252 - when running under iOS 11. Under iOS 12, the OAuth2 implementation uses ASWebAuthenticationSession, which is the successor of SFAuthenticationSession. Benefits of using 34
these APIs include: • Privilege separation: web content is run in a separate process • Trustworthiness: apps can’t inject code into or access the contents of the web view • Convenience for the user: cookies from Safari are available to the web content inside the session Connections URL Limits Using MDM Configuration, server URLs can be pre-filled or "hard-coded" as the only allowed server URL. Redirects Redirects during login are not followed silently. Instead, they are reported to the user and must be explicitly approved. SSL/TLS Certificates When adding servers, users have the opportunity to view a detailed summary of the server’s SSL/TLS certificate before they are prompted for credentials or authentication via OAuth2. If a SSL/TLS certificate fails trust evaluation (e.g., because it’s self-signed or signed by an unknown Certificate Authority), the user is given an opportunity to: • View a detailed summary of the certificate, by clicking on the notification. • Trust the certificate, despite the warnings, by clicking [ Approve ]. • Reject the certificate, by clicking [ Cancel ]. In the case of redirects across several HTTPS servers, users are given the opportunity to review the certificates of all servers involved in addition to the redirects. MDM Configuration support is planned for: • Pre-approving specific certificates and certificates with specific public keys. • Allowing only connections with specific certificates or certificates with specific public keys. 35
Inspecting Certificate Details If users want to inspect the details of an approved security certificate, from the Accounts list, swipe left on the account that you want to check the certificate of and click [ Edit ]. Then, click the row [ Certificate Details ]. You will then see the certificate’s details, starting with the validation status. More Information For more information, please refer to the security information. Data Separation Separate directories are used for the data of every server connection. This provides the following benefits: • A strong barrier against accidentally spilling data between different connections. • All data relating to a connection can be deleted by deleting the respective directory. Encryption The app uses the filesystem encryption built into iOS. Using the CompleteUntilFirstUserAuthentication file protection, data can’t be accessed after a restart until the device has been unlocked once by the user. Sync The Sync Strategies, planned to be used in the app, focus on preventing data loss locally and remotely. Secure Document View HTML and Microsoft Office document content is viewed using WKWebView, which renders the content in a separate process. Additional hardening is achieved by disabling JavaScript and blocking all network requests, which protects against lesser known, non-obvious attacks like CSS Keylogging. Passcode Users can set a Passcode to control access to the app. Find out more about this in the Passcode section of the Settings documentation. Miscellaneous Continuous Integration (CI) Continuous Integration tests verify that central security mechanisms and assumptions work as 36
expected, covering areas such as redirections, certificate handling, common Man-in-the-middle (MITM) attack scenarios, and the secure storage of authentication secrets. SQL Injection To protect against SQL injection attacks, parameters are never made part of the SQL statements themselves. Instead, placeholders are used and the parameters are subsequently bound to the SQL statements. For example, instead of running a query, such as SELECT * FROM users WHERE name='John Doe', the query would be parameterised, such as: SELECT * FROM users WHERE name=:nameToSearchFor. Reproducibility The build script that created the OpenSSL binaries used in the app is available in the SDK’s GitHub repository and can be used to reproduce the build result. OpenSSL is used solely to provide detailed summaries of SSL/TLS certificates - functionality that iOS is currently missing. Planned Logging Feature (not included in released yet!!) When logging information, parts of the log message can be tagged as private. If "Mask private data" is enabled, under Settings › Logging (it is by default), these parts will be - before the log message is written - either replaced with «private» or a trimmed version that doesn’t contain privacy-sensitive information. An example for the latter would be an NSError object’s error message containing the names of the item it is about. If masked, only the error’s error domain and error code are written to the log, but not the error message. 37
iOS Frequently Asked Questions (FAQ) Introduction Here you can find some of the most frequently asked questions about the ownCloud iOS app. Usage Compatibility With ownCloud Server Older Than Version 10.0 Previous ownCloud iOS app with support for ownCloud Server < 10.0 is still available in App Store. Compatibility With iOS Versions Older Than iOS 12.0 Previous ownCloud iOS app with support for iOS < 12.0 is still available in App Store. Login With TOTP and Other 2FA ownCloud server must have the OAuth2 app installed, configured, and enabled to use Two-Factor Authentication. Please contact your ownCloud administrator for more details. Feature Requests FileProvider: Access Full Folder, Not Only Single Files This seems like a bigger challenge for us. We track the status here: https://github.com/owncloud/ios-app/issues/604 FileProvider: Support "Recent items" and "Favorites" To support "Recent items" and "Favorites" in the iOS Files app, implementation of the Working Set is needed. This is one of the next roadmap items, but there’s no ETA yet. Text Editing Inside the iOS App Currently this isn’t a planned feature. Focus is more to build the best integration in serious 3rd party text editing app. Here you can find previous discussions: https://github.com/owncloud/ios-app/issues/317 Missing Translations or Translation Bugs You can help translate in your language or fix a bug.

Appendices In this section, you find supporting information. Mobile Device Management (MDM) Introduction Starting with iOS 7, Apple added support for managed application configuration. An MDM server can push a configuration to the iOS App. The app can access this configuration (read-only) using the NSUserDefaults class by reading a configuration dictionary under the key com.apple.configuration.managed. An app can also observe a system notification (NSUserDefaultsDidChangeNotification) to get notified about configuration changes. In addition feedback can be queried back by MDM server. To enable that, app has to write a dictionary with feedback information into user defaults under com.apple.feedback.managed key. The configuration is basically a key-value dictionary provided as a .plist file. Configurable Settings ownCloud App implements a mechanism internally called Class Settings which can be derived from different sources: • Environment variables which e.g. can be set in Xcode for testing. In this case setting keys have to be prepended with oc: prefix. • User preferences accessed by the very same API but stored under org.owncloud.user-settings key. • Settings dictionary pushed by an MDM Server and accessible using NSUserDefaults API under the key com.apple.configuration.managed. • Default settings defined directly in the app sourcecode. • Branding.plist which is the part of the Xcode project under ownCloud/Resources/Theming. It allows to override class settings by specifying them in the Configuration section This is also an order in which these settings take precedence (environment variables have highest priority). So, when settings are accessed, they are merged and higher priority value for the same key overwrites lower priority ones. Some settings are accessed only once at runtime and the read value is cached, so that new setting to take effect may a require an app to be terminated and restarted. App Basic Configurations There are few settings allowing to mark an app installation as BETA and e.g. to supress UIKit animation and review prompt. 40

Extensions are used to implement menu actions mostly found under "+" menu allowing to add new items (Upload media, take photo etc.) or in more menu (Copy, Move, Open in etc.). Using below settings actions / extensions can be disabled. Extensions are enabled by default, however this might depend on licensing requirements of a particular extension. 41
